vertboot {snowboot}

Bootstrapping a Network with Vertex Bootstrap

Description

This function bootstraps the original network using a vertex bootstrap technique. See Snijders and Borgatti (1999) and Chen et al. (2018).

Usage

vertboot(m1, boot_rep)

Arguments

m1

An adjacency matrix of the original network.

boot_rep

A positive integer number, the number of bootstrap replications.

Value

A list of bootstrapped networks as adjacency matrices.
